Patented Feb. 9, 1932 UNITED STATES FRITZ SEEBACH, OF ERKNER-IBERLIN, 'GERMAINY, ASSIGNOR T0 BAKELITE GESELL-' SCHAFT MIT BESCHRANKTER ELAFTUNG, OF BERLIN CHARLOTTENBURG, GIElRflTMIAId'Yv PROCESS OF PRODUCING OIL SOLUBLE PHENOIQ ALDEHYTJE CONDENSATION PRODUCTS No Drawing. Application filed December 27, 1927, Serial No. 242,970, and in Germany January 3, 1927.

In .my previous application Ser. No. 239,008, filed December 9, 1927, Patent 1,809,732 issued June 9, 1931, I have described a process of producing oil soluble phenol aldehyde condensation products. According to this process phenol aldehyde condensation products are caused to react in the heat with phenols containing more than one benzene ring, or phenols containing more than one hydroxyl and one or more benzene rings. The condensation products so obtained may be dissolved with oil' by boiling, but they also form-colloidal solutions by .cold mixing with fatty oils or varnishes.

The present process of producing oil soluble condensation products and solutions of same in fattyoils facilitates the formation 'of colloidal solutions of the condensation products in fatty oils and varnishes or increases the dispersity of the resins in such solutions. The process consists in combining phenol aldehyde condensation products with phenols containing more than one benzene ring or with phenols with more than one hydroxyl and one or more benzene rings and ural resins to the condensation products produced according to my application Ser. No. 239,008, filed December 9, 1927, and Idissolve the condensation products, obtained according to my application Ser. No. 239,008, filed December 9, 1927 in fatty oils and varnishes in presence of natural resins. Suitable natural resins are for instance colophony (rosin), 'dammar-res'in, dragons-blood, copal, mastic, shellac, grass-tree gum (acaroid). The advantageous action of natural resins on the formation ofcolloidal solutions of the condensation products in fatty oils and var nishes is unexpected and surprising. The chemical combination of natural resins with the-condensation products evidently does not take place. in the dissolving of the condensation products, obtained according to my application Ser. No. 239,008, filed December 9, 1927 in.

fatty oils or varnishes act as protective col loids.

.The process may also be carried out by adding the natural resins to the raw mate- I add for instance nat-,

rials of the oil soluble condensation products erating the reaction. From the condensation products so obtained solutions in fatty oils and varnishes may easily be produced.

The production of condensation products according to the present process may be carried out according to the methods described inmy application Ser. No. 239,008, filed Decemher 9, 1927, eitherunder application of catalyzing agents as hydrated oxide of manganese, lead oxide or withoutcatalytic agents. Furthermore, the phenols containing more than one benzene ring orphenols with more than one hydroxyl containing one or more benzene rings may be combined with phenolaldehyde condensation products which are capable of hardening or not capable of hard ening.

Example 1 100 kilos of a phenol aldehyde condensation product,

40 kilos of ,B-naphthol, I 0.5 kilo of hydrated oxide of manganese,

are molten at 140-150 C. for 10 minutes and,

the main reaction being completed, molten with 50-60 kilos of colophony at the same temperature. v

EmampZeQ v 100 kilos of a phenol aldehyde condensation product,

40 kilos of ,B-naphthol,

60 kilos of colophony,

0.5 kilo of hydrated oxide of manganese are molten at 150 C. and the temperature is maintained for 30-60 minutes. It seems as if the natural resins In the case of both examples the catalytic agent (hydrated oxide of manganese) may be left out. ,B-naphthol may be replaced by a-naphthol, diphenols, xanthen, dioxidibenzyl', dicresols and their homologues or resorcin.

Instead of colophony the same quantities or dammar-resin, dragons-blood, copal,

mastic, shellac, grass-tree gum (acaroid) or their mlxtures may be used.

Ewample 5 The condensation products are produced according to my application Ser. No. 239,008, filed December 9, 1927, for instance 100 kilos of condensation products capable of hardening are heated with kilos of ,B-naphthol and, the main reaction being completed, the temperature is maintained at 260 C. for 1 hours.

Thereupon after cooling the mass 60 kilos of pulverized natural resin are added and the wholewell mixed and cooled.

Example 4 120 kilos of phenol formaldehyde resin, capable of hardening, 120 kilos of phenol formaldehyde resin (Novolak) not capable of hardening, kilos of ,B-naphthol, kilo of hydrated oxide of manganese are heated and, the main reaction being completed, the temperature is maintained for 10-15 minutes at 140 C., and the mass discharged into a receptacle. After cooling the resin is pulverized and then mixed with 50-60 kilos of the above mentioned natural resins.

Example 5 kilos of fusible phenolaldehyde condensation product capable of hardening,

' 20 kilos of resorcin,

40 kilos of colophony, are molten at 130-170 C. for 1020 minutes. After eliminating the aqueous vapours a hard oil solubleresin is obtained.

The process may alsobe carried out by dissolving the natural resin in a fatty oil or in a varnish and thereupon mixing or grindin accordance with my application Ser. No. 239,008, filed December 9, 1927.

The mixing of the condensation product obtained by adding natural resin or the mixing of the mixture of condensation product and natural resin in oil or varnish,'as for instance linseed-oil, linseed-oil-varnish,

poppy-seed-oil, wood-oil, castor oil, soyabean-oil, may be effected in the usual way, for instance by boiling or mixing. Diluting agents as turpentine spirits, benzene, alcohol, acetone, carbon tetra-chloride, camphor oil or the like may also be used for producing the solutions.
